The lines represented by the equations 20y−24x=−20 and 5y−6x=−5 are... a)perpendicular
b)the same line
c)neither parallel nor perpendicular
d)parallel

Choice B

Step-by-step explanation:

The best way to compare two lines is to solve for y.

The first equation:

For the first thing we should do is add the 24x on both sides which will cancel out itself on the left side . Now all we have to do is divide the 20 on both sides to leave us with .

The second equation:

For the first thing we should do is add the 6x on both side which will cancel itself on the left side . Now all we have to do is divide the 5 on both sides to leave us with .

Now for the comparison:

They are the same exact line. If you were to graph them they would overlap each other.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
